They are over secure themselves. The raison is the health system. No proof although that if you got once Covid you can not get it second time or just be carrier/asymptomatic. Same goes for the vaccines.This must be a joke.
You must quarantine for 14 days even if you:
- have tested negative for COVID-19
- have been vaccinated for COVID-19
- recovered from COVID-19
A friend of mine arrived in the beginning of January in Toronto. They stayed 14 days in quarantine and 3 days later all of them got Covid. Total mystery!
